DynVer Breaks on SemVer Tags with Metadata

[apeschel]

DynVer doesn't respect tags with build metadata in them. SemVer tags with a + in them completely break DynVer.

Metadata SemVer tags

Input:
v1.2.3+foo
Expected Result:
Ignore tag or Valid SemVer version (maybe use v1.2.3-13dcda87+foo.0 instead?)
Actual Result:
Invalid SemVer version v1.2.3+foo+0-13dcda87

Ouch! Sorry about that. Is this something you'd like to send a fix for? I don't know if I'll have time to get to it in the immediate future.

[apeschel]

I'll try to come up with a patch if I have time in the next week or so.
